Python generates examples of password library functionality

This article illustrates the ability of Python to generate a password library. I will share it with you for your reference as follows:

This code is to add all the combinations of characters into a file, you can set the maximum length of the password, I set 8 bits here, but be prepared, the generated file is very large...

Here's the code for python:

#!/usr/bin/python
import string
letters = string.letters + string.digits + string.punctuation
length = len(letters)
fwrite = open("/tmp/genpass.txt","wt")
fread = open("/tmp/genpass.txt","r")
for num in xrange(8):
    for times in xrange(length**num):
        line=fread.read(num+1).rstrip()
        for letter in letters:
            fwrite.write(line + letter + "\n")
    fwrite.flush()
fwrite.close()
fread.close()
